1 Claim. 1

This invention relates to safety snap.

It is an object of the present invention to provide a safety snap which is so constructed to fit under a piece of clothing or cloth and with a cooperating element which will contain the first snap element and the cloth, whereby to secure the two elements and the cloth portions together.

It is another object to provide a safety snap device for use on clothing and to eliminate the use of the standard safety pin which has a pointed end.

Other objects of the invention are to provide a safety snap arrangement adapted to contain clothing or cloth which is of simple construction, inexpensive to manufacture, has a minimum number of parts, and is compact, easy to operate and convenient to use. I

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which: v

Fig. 1 is a collective and perspective view of the two elements forming the safety snap designed according to one form of the invention.

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1 with the parts in assembled relationship.

Fig. 3 is a collective view of the several parts of the fastener separated from one another and shown in perspective, the spring elements being separated and released from the projections of the one part.

Fig. 4 is a top planned view of the one part containing the spring elements.

Fig. 5 is an enlarged vertical sectional view of a safety snap according to another form of the invention, wherein projections of thesprings are provided to effect the release of the parts.

Fig. 6 is a fragmentary perspective view of the spring assembly part with a section thereof removed to show the spring with its projection in full perspective.

Referring now particularly to Figs. 1, 2, 3 and 4, ll! represents one of the snap elements which has a central projection or protrusion ll over which the cloth is placed. This element may have a plurality of small holes l2 for the purpose of attaching it to a garment by means of the passage of thread through the holes and to the garment material.

A second element I3 is formed of an assembly of a backing part l4, opposing springs l5 and I6, and a cover part [1. The backing part has an upstanding peripherial flange I 8 and a central opening l9. Also, struck upwardly from within the part are a plurality of struck up portions or tabs 2| arranged in pairs and each pair adapted to receive and retain either a spring IE or a spring IS. The spring l5 has an intermediate portion l5 and two end portions |5a and I51) formed of a reverse curve from the intermediate portion l5. The spring element It has an intermediate portion I6 and reverse curved end portions l to and lb. These spring elements are fitted into the part I l outwardly of the struck in tabs in the manner asshown in Fig. 4. The intermediate portions will extend inwardly beyond the edge of the hole Hi. i a

The part I! of the assembly l3 has tabs 22 angularly spaced from one another and these tabs extend about the flange I8 of the part or member M. These tabs will lock the parts 14 and I! together. This member I! has a hole 23 equal in size to, the hole I 9 of the member 14. Small holes 24' are provided in the part I! by which the assembly can be fixed by means of.

thread to a garment or cloth material.

' It will be seen that the springs are located in the base part It and are centered in position by the struck portions 2| and the flange l8. Part I! is placed over the part I l and held in assembled position by bending the tabs.

The head of the member I 0 is pushed into the openings 19 and 23 of the respective parts l4 and i1 and will press outwardly the springs l5 and I 6 and the intermediate portions l5 and Hi of the respective springs will retain the head ll of the member Hi. When the pressure on the spring is released the springs return to their original positions. As the head I l is pulled from the assembly, a similar deflection of the springs l5 and I6 is made. The holes [9 and 23 are sumciently large so that a cloth can be projected through the same by means of the head II.

The arrangement is particularly adaptable for connecting together the ends of diapers and similar cloth material. The arrangement will get away from the safety pins which are ordinarily used on babies diapers and provide a more safe means.

Referring now more particularly to Figs. 5 and 6, there is shown an arrangement wherein the springs can be levered in such a manner as to be easily released from the head and without having to force the parts of the fastener assembly from each other. According to this form of the invention there is provided a body member 25 having a head 26 with a sharp shoulder 26'. The assembly, including a part 28 and a part 29, held together by tabs29' and which respectively have openings 3| and 32 to receive the head 25. These openings 3| and 32 are sufiiciently large to receive a cloth with the heading 26.

Special spring elements 33 and 34 are used. These spring elements are held by projections 35 struck inwardly from the flanged member 28. Each spring element has an intermediate portion and reverse curve end portions which are attached to the tabs 35. On the intermediate portion of each spring element is ahandle projection 35 which has an enlarged end 36' and which can be levered to pull in the intermediate portion of the spring and to release the head 26. The handle projection. 36- extends through diametrically-spaced holes 3? and 38 in the part 29 and can pivot against the sides of the holes. By grasping the two projections 36 which extend outwardly from the springs 33- and 34, the intermediate portions of the springs will be levered from the shoulder 26. This will release the head 2'8 and permit the members to be disengaged from one another; As soon as the handle projections 35 are" released, the springs will assume their original shapes and prepare the same for the next insertion of the head 26; It will thus be apparent that the 'parts can be more quickly severed from one another by a simple squeezing together of the handle projections' 36.

Whilevarious changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the appended claim.

We claim:

A- snapfastener assembly comprising a body member having an enlarged-central head projecting' therefrom, said central head having a peripheral shoulder, an assembly adapted to receive' said head and comprising two parts fastened together, one of said parts having inward- 40 ly-extending; projections arranged in pairs spaced apart from one another, opposing spring elements, each of said spring elements having a bowed intermediate portion adapted to engage the peripheral shoulder of the central head of the body member and reversely bowed end portions, said pairs of projections of the one part receiving the reversely bent end portions of the respective spring elements, said body member further having a peripheral flange and the reversely'bowedend portions of the spring elements being confined between the flangefland the projections, the other part being fastened to the one part and confining said spring elements therebetween, said assembly parts having registered central openings for receiving the head of the body member, the intermediate portions of -therespecti-ve spring elements extending inward- 151' of the periphery of the registered central opening, said one part having diametrically spaced holes disposed respectively at the opposite sides of the central opening of the other part and each of said spring elements having forwardly-extending. projections extending. respectively throughsaidfdiametricallyspaced holes and operable whenr levered radial-1y inwardly on the sides of said holes to release the springs fromtheperipheral shoulder of the. central head whereby upon squeezing together. said handle. projections the assembly may be quicklyand easily separated from bodymember.
